Packaging container with humidity indicator

Abstract

A packaging container including a humidity indicator system specifically designed for use in packaging electronic circuits, such as integrated circuits. The packaging container is prepared from a water and water vapor proof, anti-static packaging material and contains an opening therein. The humidity indicator system includes a humidity indicator element, a humidity comparison element and a securing system for securing the humidity indicator element to the packaging container, wherein the opening in the packaging material is closed by the humidity indicator system.

We claim: 
     
       1. A packaging container with sides containing a humidity indicator system comprising an anti-static, water and water vapor proof packaging material with edges, wherein a plurality of the edges of said packaging material are secured together to form a packaging bag with an inside surface and an outside surface, wherein an opening is present in one of the sides of said packaging bag, and   a humidity indicator system comprising a humidity indicator element and a securing system, wherein the securing system comprises an inner sealing ring and an outer sealing cap for securing the humidity indicator element to the packaging bag, wherein said securing system is moisture and vapor proof, and wherein said securing system closes the opening in said packaging bag.   
     
     
       2. The packaging container of claim 1 wherein the humidity indicator system further comprises a humidity comparison element. 
     
     
       3. The packaging container of claim 2 wherein said securing system comprises a clear, plastic element with an inside surface and an outside surface, wherein said clear, plastic element is secured to the packaging bag to close the opening and wherein said humidity indicator element and humidity comparison element are secured to the inside surface of the clear, plastic element. 
     
     
       4. The packaging container of claim 2, wherein the humidity indicator element and humidity comparison element are secured to said inner sealing ring. 
     
     
       5. The packaging container of claim 2, wherein the humidity indicator element and humidity comparison element are secured to the outer sealing cap. 
     
     
       6. The packaging container of claim 1, wherein said outer sealing cap is secured to the packaging bag. 
     
     
       7. The packaging container of claim 1, wherein said inner sealing ring and outer sealing cap are secured together.
